I UNITED STATES PATENT OFFICE JOSEPH H. FISCHER, OF CHICAGO, ILLINOIS.

OXYGEN-CELL.

.Beit known that I, JOSEPH H. FISCHER, a citizen of the] United States, residing at Chicago, in the county of Coolc'and State of Illinois, have invented a new and useful Improvement/fin Oxygen-Cells, of which the" and cathode.

The object of, my'invention is to produce an oxyhydrogen cell which will have a very large area of active surface and in which the separation of the plates can conveniently be made uniform.

My Invention resides nation of parts hereinafter more specifically set forth. Further objects and advantages will be made evident hereinafterg Referring to the drawings, which are for illustrative purposes only, Figure 1 is an sulated bolts a "section" on 'a elevation partly in section on a central plane of a cell einbodyingmyinvention.

Fig. 2' is a section on a plane represented by line 22.Fig. 1, this p ane-lbeing viewed in the-"direction of the arrows. Fig. 3 is lane represented by line 33 of' Fig. .14, this, plane" belng viewed in the direction of the arrows. Fig; 4 is'a section on a plane represented byline 41 of Fig. 4, this plane beingviewed in the direction of the arrows; Fig. 5 is anelevation partly in section on a plane at right In the fornnof the invention illustrated in the drawings, .the cylindrical shell 11 is provided with a flange 12 on the upper end thereof and a flange. 13 on the lower end thereof.- Secured to the flange'13 by in- 14 is a" cast base 15'which is electrically insulated from the flange 13 by any suitable sort of insulating. material 16.

Spaced apart, centered and supported by the glass insulators 25 are two concentric anode cylinders which are also spaced apart at various points around their circumference by spacing blocks 31.

At le st one of these spacing blocks 31 must forming a convenient point for the attachment of the anode terminal 32. The cylinders 30 form what may be con veniently termed the anode of the'cell, the drum 21 and the shell 11 forming the Itwill be noted that members 11, 21 and g It is comparatively easy to form metal members which are nearly cylindrical and particularly where they are braced together by spaces similar to the spaces is, therefore, comparatively easy to' make the annular 31in cylinders 30. It l spaces, formed between the anode and cathode of quite uni-form thickness so that the passage of tween will be fairly uniform- Secured on the flange 12 is a top 40 which may conveniently be a casting the anode terminal 32 passing therethrough and being insulated therefrom by suitable insulation 11. Each of the anode terminals 32 may be connected through a strap 1-2 with a cathode terminal l3, each of the cathode terminals 43"b'eing secured in electrical contact with a bent strap 44 secured to the shell 11.-

Cast in the top 40 is an upper drum 45-.

Secured to the inner apron support 16 is .an asbestos (or. other fabric) similarly secured to outer apron support 17 is an outer apron 49 also formed of-asbestos or other fabric. Aprons 48 ahd149 extend to the bottom of the cell.

Formed in the cast iron top '40 is an; oxy gen opening 50 which communicates through an bpening 51 with the space between the two, aprons 48 and 519, "through which the 15 are cylinders 46 apron 48 and X oxygen gas is fed to the oxygen tube 52,"

communicating with the seal 53. Also,

formed on the top 12 is a hydrogen opening 54 which communicates through openings 55 and 56 with the space outside the apron 49 and inside the apron 18, hydrogen being delivered through the opening 54 to the tube 57 communicatingwith the hydrogen seal 58.

The seals ;53 and 58 are similar in' con struction, each consisting of a 'base 60 having afilliiig opening 61 and an overfiow opening 62 therein.
